Re: Exhaust sound
I was not complaining about the sound it makes 2000 to 2500. It is a great sound and folks outside take notice of the car realizing that maybe this c4 is something different. (My ZR-WON plates help). I wish that GM had made the outside look as different as the engine looks!

Re: Exhaust sound
I'm pleased that our Z's appear almost as though they are just another C 4. The surprise and jaw dropping facial expressions of challengers makes the sameness of the 'Vettes worthwhile. It's almost a "I can't believe this is happening" experience for them.

Re: Exhaust sound
The modded ZR1's put the C6 ZO6 in the rear view mirror. Now that is a jaw dropper
 My modded ZR1 has run neck and neck against my head/cam etc. C6 ZO6. ---------------------------------------------------------------------- Gibby........I have to check out these DynoMax VT mufflers. Call me old I dont give a crap but sometimes I want QUIET.

Re: Exhaust sound
My stock motor ZR-1 never lost to the early C5 ZO6's. Then came the '02 version, and I couldn't keep up with them.
Now I'd have to go for one of Marc's 500+hp. tunes just to keep up with the base motor C7. The King can't stay on top of the hill forever.  Borla is the sweetest sounding exhaust I've ever had on the car. Performance?...not so much.

Re: Exhaust sound
The stock exhaust is pretty quiet, until you get into the 3500 to 4000 mark when it starts making pretty good sound.
When I was running the stock exhaust at the drag strip, I was told there was a big difference in sound between the ZR-1 with the stock exhaust and other Vettes. I don't think it would make someone really take note of the car on the street, though, like what the OP is describing with his system.

Re: Exhaust sound
If borla exhaust is somewhat restrictive. Would it be similar to stock exhaust in terms of restriction?
